NP-hard problems are not as hard as you think
NP-Overrated
Many developers believe NP-hard problems are intractable, but in practice they're often solvable quickly. This post argues that worst-case complexity is rarely relevant, citing examples like package dependency resolution, type checking, scheduling, and SAT solving. It highlights algorithmic advances that have led to massive speedups, and notes that even Amazon solves a billion SMT problems daily.
In theory, there is no difference between theory and practice. But in practice, there is.
